Senior Software Engineer — C++ · Python · JavaScript · AI · Browser Extensions
Senior Software Engineer and Architect with deep expertise in secure, high-performance measurement platforms and cross-browser extensions. Proven track record modernizing legacy systems and driving product evolution at Comscore and TCS (Nielsen), backed by equity trading systems at Morgan Stanley and award-winning TTS technology.
With over 20 years in software engineering, I specialise in building secure, high-performance platforms where reliability and privacy are non-negotiable. My core work has been in audience measurement — developing browser extensions and Windows applications used by millions of panellists across Chrome, Edge, and ChromeOS at Comscore and Nielsen.
Earlier in my career I co-developed Vaachak, a Hindi and English TTS engine that earned India's National Award for Empowerment of Persons with Disabilities — later acquired by Nuance/Microsoft. I also built high-frequency equity trading infrastructure at Morgan Stanley. Most recently I designed SecureView, an AI-powered Chrome extension that categorises browsing behaviour using Amazon Bedrock via a serverless AWS pipeline.

A Chrome Extension (Manifest V3) that tracks active browsing time per site, automatically categorises every domain into one of 11 categories (Technology, Entertainment, Productivity, and more), and surfaces the data through a clean popup with daily history and search. For sites that cannot be classified by rule, it falls back to Amazon Bedrock via a serverless AWS pipeline — keeping the API key entirely server-side. Built with pure vanilla JavaScript; no build step, no dependencies.
